Aim: To assess the influence of two adhesive systems on the bond strength of the restorative material to enamel and dentin after bleaching. Materials and method: 60 non-carious extracted premolar teeth after bleaching with 40% Hydrogen peroxide were divided into four groups based on type of adhesive system used and the tooth surface i.e. enamel and dentin used for bonding. G1ET and G3DT were re...

AIM To evaluate whether application of a total-etch/separate adhesive layer can enhance the bond of a UDMA-based sealer to dentine. METHODOLOGY The root canals of 20 decoronated maxillary premolar teeth with two canals were prepared to size 35-45, 0.04 taper using rotary NiTi instruments. The canals of each tooth were treated with application of either a total-etch/separate adhesive or the ma...

INTRODUCTION The adhesive systems and the techniques currently used are designed to provide a more effective adhesion with reduction of the protocol application. The objective of this study was to evaluate the bond strength of universal adhesive systems on enamel in different etching modes (self-etch and total etch). MATERIALS AND METHODS The mesial and distal halves of 52 bovine incisors, he...

OBJECTIVES This study investigated whether increasing the concentration of acidic monomers in one-step adhesives would allow reducing their application time without interfering with the bonding ability to primary enamel and dentin. MATERIAL AND METHODS Experimental one-step self-etch adhesives were formulated with 5 wt% (AD5), 20 wt% (AD20), or 35 wt% (AD35) acidic monomer. The adhesives were...

Objective The purpose of this study was to investigate the effect of silver nanoparticles on composite shear bond strength using one etch and rinse and one self-etch adhesive systems. Material and Methods Silver nanoparticles were prepared. Transmission electron microscope and X-ray diffraction were used to characterize the structure of the particles. Nanoparticles were applied on exposed den...

OBJECTIVES The aim of this study was to compare the technique sensitivity of a one-bottle total-etch adhesive and a self-etch primer adhesive to the moisture condition of the dentine substrate. METHODS The methods used were hydraulic conductance, light microscopy and scanning electron microscopy. RESULTS When the moisture conditions of the dentine surface are modified with respect to the st...

AIM Core buildup composite resins with prefabricated posts are commonly used to restore endodontically treated teeth. This study compared the sealing ability of Core Max II and Panavia F2.0 cement with total-etch and self-etch adhesive systems. METHODS AND MATERIALS Sixty recently extracted human second premolar teeth were chosen and their crowns were cut 3 mm above the CEJ. After preparing p...

background: esthetic demands among patients have led to the introduction of tooth-colored restorations. composite resins bond to enamel applying acid etch technique. total etch adhesion systems are still considered as golden standard among bonding systems. however, clinicians have tendency towards using adhesive systems with a simplified application procedure. the aim of the present study is to...

OBJECTIVE The objective of this study is to evaluate the effect of irrigating agents on push-out bond strength of resin postcemented with various adhesive systems at different radicular dentin sections. MATERIALS AND METHODS Sixty single-rooted premolar teeth were root canal treated, subsequently decorated at cementoenamel junction. The endodontic postspace was irrigated with 5.25% sodium hyp...
